Also interesting point, it makes me think perhaps that is what teardrops are made to solve while still having some aerodynamic qualities of rifled biconicals?

Properly rifled  at the right angle for distance I believe biconicals do fall point first into the dirt I've had this happen. But they need the initial right yaw angle and launch angle.  Not all styles, grips or slings make this easy.

So I got myself into the testing. I tried teardrops with several styles of throw and sling. Still biconicals seemed to fly the furthest out of all the ammo shapes I made with my preferred balearic style and balearic slings. Maybe the way I achieve rifling with those slings makes biconicals better shape?


However, I tried it with slings and styles I don't get as good pouch control with as I do with my preferred slings and teardrops seemed to work better than biconicals.
With my clothing line slings and paracord slings I find it hard to get good pouch orientation control so with biconicals I sometimes get them to go sideways, which decreases the range greatly.
With those slings I usualy use the fig 8 or helicoper or greek throw, and teardrops seemed to stabilise in flight better than ovals or biconicals with bad pouch orientation while flying further than balls.


They seemed to work the best with very simple belt leather and clothing line sling with byzantine style throw. With sling just little longer than my arm getting them to around 200m.(the same sling got me about 150m with just balls)

I don't think my conclusion is objectively right, this is just from my testing with different slings. Other people might report differently with their own styles or different slings, grips, etc...

This is best seen in staff slinging. Lighter clay balls with staff sling get really great range and you can clearly see how they fly straight and then lift a little bit.

heres a little openscad scriot for playing around with teardrop shapes.

Anyone makes one they'd like a mould for - let me know

copy and paste the below into openscad: www.openscad.org

hit f5 to see the shape.

That got me wondering, how far would a good sling throw go on the moon? 60 m/s would go about 2200 m. That's a fair toss!( if you could keep your mechanics correct in 1/6 gravity)

Actually, that's almost to the horizon. For someone 1.8m tall, the horizon is about 2500m away. 

Aerodynamic has no meaning on the moon, it's a Vacumn
Zero atmosphere.
So all you have to contend with is light gravity.

So a really light missile is what you would want.
And a really long sling.

You could throw a sponge further than a lead glande !
That takes some getting your head round

Overall weight is pretty much the only thing that counts.
And being able to get a good release from the sling pouch.

But you could use a sling 10 feet long really easily.
It's gravity and air resistance that limits sling length on earth.
But not on the moon !

The kind of release velocity you could achieve is mind blowing.

But surely the race for the vaccine ended on the moon ?

I'm going with the holographic projection, as I've not heard that before lol.
